I feel like psychometrics is uniquely bad at naming things. Parallel, congeneric, tau-equivalent, essentially tau-equivalent measures? Configural, metric, scalar, residual invariance? Item difficulty defined so that the higher the difficulty, the easier the item???

Identifying flaws in GenAI unfortunately offers a pretext for claims that perfecting the product is just a matter of time & money. So pointing to chatbots’ role in,say, suicides can only go so far if we don’t also identify the systemic, irresolvable lack of Gen AI’s human commitment bc math has none

Initial release of #Rstats 📦 {piecemeal} for wrangling large simulation studies is now on #CRAN . A demo here: cran.r-project.org/package=piec... . I believe that brings me up to 10. 😅

This is great. I am not a fan of the oscillator example - makes it seem like a physics niche thing. But so useful for us population-thinkers. I might write up a post using a population dynamics differential equation example. If I can finish cloning myself. Yeah. www.youtube.com/watch?v=FE-h...

Mitte-Studie 2025 - So verbreitet sind rechtsextreme Einstellungen
Wirklich rechtsextrem ist in Deutschland nur eine kleine Minderheit. Aber: Viele teilen anschlussfähige Einstellungen zu Nationalstolz oder politischer Gewalt.
